156 Report of the Department of Bacteriology of the 



Table XI. — Number of Cells Per Cubic Centimeter Found in the Milk of 

 Four Cows During a Period of Five Weeks — (Concluded). 



Numbers given in thousands per cubic centimeter. 



The records of the four animals are given in Table I on page 150. 

 As will be seen from this table, Hammond F. 1 was a cow in her 

 prime (5 years old) and had always had normal calvings and had 

 never had any trouble with her udder previous to this time. Her 

 last calf was born on August 27, 1910. The same statements are 

 true of Gerty F. 1, except that she was 6 years instead of 5 years 

 old. She calved on July 19, 1910.
